Damp-Heat

Damp-Heat represents a pathological condition where pathogenic dampness and heat combine, creating a complex pattern characterized by both stagnant, turbid dampness and inflammatory heat symptoms. This combination typically results from external damp-heat invasion, improper diet, or internal organ dysfunction leading to dampness generation that subsequently transforms into heat. The pattern is clinically significant due to its persistent, sticky nature that resists resolution and tendency to manifest in multiple organ systems simultaneously.

Clinical Presentation

Heavy, sticky sensations in head and body
Fever that worsens in afternoon or evening
Profuse sweating that does not relieve fever
Abdominal distention and loose, sticky stools
Scanty, dark, turbid urine
Chest oppression and nausea
Skin eruptions with suppuration or weeping
Joint swelling with heat sensation
Vaginal discharge that is yellow, thick, and malodorous
Mental agitation and irritability
Tongue: Red with thick, greasy yellow coating
Pulse: Slippery and rapid (hua shu)

Pattern Differentiation

vs. Simple Dampness

Lacks heat signs such as fever, inflammatory symptoms, yellow discharges, or red tongue. Coating is white and greasy rather than yellow. Pulse is slippery but not rapid. Symptoms are primarily heavy, sticky sensations without burning or inflammatory manifestations.

vs. Heat in Stomach and Intestines

Presents with dry heat symptoms including constipation with dry stools, intense thirst for cold drinks, and burning epigastric pain. Lacks the sticky, turbid dampness signs such as greasy tongue coating, heavy sensations, or loose stools. Tongue is red with dry yellow coating rather than greasy yellow coating.

vs. Liver Qi Stagnation with Heat

Emotional triggers clearly precipitate symptoms, with pronounced mood swings and stress sensitivity. Heat manifestations are primarily related to emotional agitation rather than systemic inflammatory signs. Lacks the characteristic dampness symptoms of heavy sensations, sticky stools, and greasy tongue coating.

Treatment Principle

Clear heat and resolve dampness through drainage and transformation. Primary actions include promoting urination and defecation to eliminate damp-heat via the lower burner, clearing heat to reduce inflammatory manifestations, and transforming dampness to restore normal fluid metabolism.

Acute damp-heat patterns typically require 2-4 weeks of treatment, while chronic presentations may need 6-12 weeks or longer. The sticky, lingering nature of dampness makes this pattern notably slower to resolve than simple heat patterns. Treatment duration depends on constitutional strength, pattern severity, and patient compliance with dietary restrictions.

Eliminate all damp-producing foods including dairy products, greasy and fried foods, excessive sweets, and alcohol. Avoid heat-generating foods such as spicy dishes, lamb, and excessive amounts of warm, pungent herbs. Focus on bland, easily digestible foods with natural diuretic properties like winter melon, Job's tears, and mung beans.

Add organ-specific points based on primary manifestation location, such as LR-2 (Xingjian) for liver damp-heat or BL-22 (Sanjiaoshu) for triple burner damp-heat.
